I wonder if some one can give me a lead to resolve this issue.
Since a couple of months my Focus starts normally in the morning, but it appears it does not have enough fuel to keep the engine running, rpm goes down to 500 or less and the engine stops. I have to push the gas intermittently to compensate for the lack of gas until the engine runs over 1500 rpm and then it works normally. This does not happen when the engine is hot.
Now I have to push the gas pedal three or more times before to start the engine, that appears to help, but it does not solve the problem. The engine can go into stalled either way.
During normal driving it tends to run at very low rpm around 700 and sometimes the engine stops while I am not pushing the gas pedal.
I was told the temperature sensor may be the issue, but I think it has to do with the fuel pump or something in the fuel system. Or maybe something related with the setting of the cruiser rpm?
I will appreciate any lead.
